Comparative Study of IRIS Boundaries Segmentation

Biometrics allows an individual to be recognized and legitimate based on a set of identifiable and provable data, which is unique and explicit to them. During the authentication process we compare the data for the individual distinctiveness to that of individual's biometric "template", which was already stored in a database of a secured portal in order to establish authentication. It further depends upon the inconsistency in processing data which includes capturing process i.e. how data is procured, treated and handled/ sampled. So it is necessary to first analyze the process of capturing and sampling of the data to understand which identification system, suits the needed biometric quality. Despite the fact that number of definitions of quality exist, but because of need of time and processes, a particular interpretation of quality is needed. In this paper we try to present an review of different detracting features, definitions’ and interpretations of qualities so that a comprehensible image of existing status can be presented by comparing features, strength and limitations of different biometric system. We further discussed the factors that control the features of biometric samples, which make the processes complicated. We tried to present different bottlenecks present in system design for various applications.
